Hecher

The official Model Context Protocol (MCP) server for Hecher — the multi-tenant CRM for Chabad shluchim by Grow Gelt.

Connect Claude Desktop, ChatGPT, Cursor, or any other MCP‑compatible AI assistant to your Hecher account and let it search donors, record donations, run reports, and manage tasks for you — across all of your organizations (mosads).

Heads up: This repository is the public listing and documentation for the Hecher MCP server. The server itself runs as a managed remote service at https://api.hecher.app/mcp — there is nothing to install or self-host.

---

Quick start

1. In your MCP‑compatible client (Claude Desktop, ChatGPT, Cursor, etc.), add a new remote MCP server with this URL:

   https://api.hecher.app/mcp
   

2. The first time you use it, your browser will open and ask you to sign in to Hecher and approve the connection.

3. Once approved, the assistant can act on your account.

You can review and revoke connected assistants anytime under Settings → AI Connections inside Hecher.

What it can do

The server exposes 20 tools that wrap the Hecher API. Every call runs as you, in whichever Mosad you've selected as active — RLS, billing gates, and audit logging all apply exactly as in the web app.

Organizations (Mosads)

• list_tenants — list the Mosads you have access to
• set_active_tenant — choose which Mosad subsequent calls operate on
• get_active_tenant — show the currently active Mosad

Donors

• search_donors — search by name, email, phone, tag, or status
• get_donor — full profile with stats and contact info
• create_donor / update_donor / delete_donor
• add_donor_tag / remove_donor_tag / bulk_tag_donors

Donations

• list_donations — optionally filtered by donor or date
• create_donation / update_donation / delete_donation

Activities & tasks

• list_activities — optionally filtered by donor, status, or assignee
• create_activity — task, call, meeting, or note
• complete_activity

Reporting

• get_dashboard_stats — KPIs for the active Mosad
• run_report — execute a saved report

---

Authentication

The server speaks OAuth 2.1 with dynamic client registration, so any compliant MCP client can connect with no manual API keys.

Endpoint	URL
Discovery	https://api.hecher.app/.well-known/oauth-authorization-server
Authorization	https://api.hecher.app/oauth/authorize
Token	https://api.hecher.app/oauth/token
Dynamic registration	https://api.hecher.app/oauth/register

Each authorization issues an access token bound to your user account and the Mosad you pick during the consent flow. Tokens can be revoked at any time from Settings → AI Connections.

---

Permissions & limits

• Tools act with the permissions of the signed‑in user in the active Mosad — no privilege escalation.
• All write operations honor Hecher's billing gates and audit log.
• Per‑user rate limits from the Hecher API gateway apply.
• Bulk mutations (e.g. bulk_tag_donors) flow through Hecher's background operation queue, the same as in the web UI.

---

Compatible clients

Any MCP client that supports remote servers over Streamable HTTP with OAuth 2.1, including:

• Claude Desktop

• Any custom client built on the MCP SDKs
